摘要： A casting dope (11) prepared from CAP, additive and solvent is cast onto a casting belt (35), peeled and dried to be a primary film (14), and wound to a primary film roll (16). After the storage, the primary film (14) is unwound and fed into a tenter device (18). In the tenter device (18), while the stretch in the widthwise direction is performed, a relaxation of the primary film (14) in the longitudinal direction is made. If an extent percentage of the stretch is less than 70% to the predetermined value, the relation is started. The primary film (14) is fed out as a produced polymer film (22) from the tenter device (18), and the polymer film (22) is wound up to a product film roll (24). On the produced polymer film (22), the in-plane retardation increases and the thickness retardation decreases. Thus the optical properties become preferable.
摘要翻译：将由CAP，添加剂和溶剂制备的浇铸液（11）浇铸到铸造带（35）上，剥离并干燥成初级膜（14），并缠绕到初级膜卷（16）上。储存后，将初级薄膜（14）退绕并进入拉幅机装置（18）。在拉幅装置（18）中，在进行宽度方向的拉伸的同时，使主膜（14）沿长度方向松弛。如果拉伸的程度百分比小于预定值的70％，则开始关系。从拉幅装置（18）将初级薄膜（14）作为生产的聚合物薄膜（22）送出，将聚合物薄膜（22）卷绕到产品薄膜卷（24）上。在所生产的聚合物膜（22）上，面内延迟增加，厚度延迟减小。因此，优选光学性质。

摘要： A casting dope (27) prepared from CAP, additive and solvent is cast onto a belt (46) and peeled as a wet film (74) that is drawn in the longitudinal direction in a transporting area (80). In a tenter device (47), while the wet film (74) is stretched in the widthwise direction, a relaxation of the wet film (74) in the longitudinal direction is made. If an extent percentage of the stretch is less than 70%, the relation is started. The wet film (74) is fed out as a polymer film (82) from the tenter device (47). On the polymer film (82), the in-plane retardation increases and the thickness retardation decreases. Thus the optical properties become preferable.
